提出了一种用于工程车发动机余热驱动空调的13 X沸石-水吸附式制冷模块。测试了不同蒸发温度下组件的制冷功率,分析讨论了组件在不同制冷功率下的循环运行特性。结果表明,制冷模块的制冷性能与热源温度(Ths)、环境温度(Ta)、风速(v)和空气相对湿度(φ)等外部环境参数有很强的耦合关系。系统地进行了实验,并详细分析了环境参数对组件性能的影响。结果表明,在Thsat为325°C、Taat为18°C、φ为70%、自然对流的条件下,所研制的制冷模块具有良好的制冷性能,对应于2.0W和10.5W制冷功率的最低蒸发温度分别为0.7°C和16.2°C。在此基础上,初步提出了一种适用于工程卡车驾驶室的多模块吸附式空调系统。
A modified adsorption cooling module with a working pair of 13X zeolite-water used for engineering truck air-conditioning driven by engine waste heat is presented in this paper. The cooling powers at different evaporating temperatures for the module were first tested, and the cycle operating characteristics of the module at different cooling powers were then analyzed and discussed. The performance of the cooling module is found to have a strong coupling with exterior ambient parameters such as the heat source temperature (Ths), ambient temperature (Ta), air velocity (v) and air relative humidity (φ). Experiments were carried out systematically and analyzed in detail to study the effects of the ambient parameters on the module performance. Our results indicate that the demonstrated cooling module has a good performance, and the minimum evaporating temperatures corresponding to the cooling powers of 2.0W and 10.5W are 0.7°C and 16.2°C, respectively, under the conditions of Thsat 325°C, Taat 18°C, φ at 70%, and natural convection. Based on the presented module, a preliminary multiple module adsorption air conditioning system for engineering truck driver’s cab was also proposed in this work.
